APPARATUS FOR STORING AND PRESERVING BEER ON TAP.

SPECIFICATION forming part of Letters Patent No. 514,508, dated February 13, 1894.

Application filed February 211 1893. Serial No. 463.] 97. (No model.)

To and whom it may concern:

Be it known that I, Orrnnnns SHABLEY, a citizen of the United States, residing at La Salle, in the county of La Salle and State of Illinois, have invented a new and useful Improvenient in Apparatus for Storing and Preserving Beer when on Tap, of which the following is a specification.

My invention relates to apparatus for storing the beer when on tap and its object is to preserve the beer from the air and prevent the evaporation of its gases and to provide for ready and strong flow of the beer when being drawn from the vessel, and consists in the mechanical elements and combinations set forth in the claims hereof.

Reference will be had to the accompanying drawings, in which Figure 1 is a side view of the machine. Fig.2 is a side sectional view. Fig. 3 is a side view transversely of Figs. 1 and 2. Fig. 4 is a plan of the lifting mechanism on the line 4, i, of Fig. 1. Fig. 5 is a plan of the stop catch mechanism. Fig. 6 is a sectional view of the vent cock.

In the drawings, A designates a cylinder, being a chamber large enough to hold the contents of a beer keg designated by B in the drawings. This cylinder is supported on abed frame A'. Over the top of this cylinder there is a yoke A resting on the edges of the cylinder, and fastened down at a to posts A fastened into the bed frame at a. In the top of the yoke A there is an aperture through which a piston rod D passes. At the bottom of this rod D there is a piston O which piston O is composed of a plate O screwed to rod D at 0 and above this on the rod D there is fastened at O another plate O and between these plates there isa ring 0 carrying packing G There is a little space at top and bottom of ring 0 between the plates 0 0' permitting an adjustment by the nut 0 of the packing G In the ring O there is acircular recess 0 extending around the ring and there are openings O O connecting this recess with the space between the plates C' C and ring 0 and in the top platethere are holes O opening into the outer air. The objects of this construction are to insure a perfect exclusion of the air from underneath the piston as water is poured on top of the plate and fills the interior space between the plates and the recess 0 thereby aiding in the packing of the piston, as no excessive pressure is exerted by the piston. In the piston rod D there are notches a? into which the pawl e operates. The pawl e is pivoted at e into alever E which is pivoted at E in the yoke A The pawl c has two engaging points a 6 to engage the notches d in lifting and in lowering the piston. The pawl e is fixed to the axis e' which articulates in the bearings of the lever E and is held in engagev .pawl e in engagement with the notches d of the rod D. The position shown in Fig. 1, the projection c rest-s against the stop a but in the dotted position of the same figure, the projection e rests against the stop e On the other side of the rod D there are notches d' into which alocking bolt F engages, to hold the rod D in any desired fixed position. This bolt F is held in en gagernent by a spring f and its outer end is beveled to permitit to slip by notches d' in one direction. To the outer end of this bolt F there is a handlef which,when the bolt is drawn back sufficiently for the end to clear the notches (Z of the rod D, may be revolved past the end f of the block f and lock the bolt F out of engagement and the handle f may be revolved to reverse the bevel of the end of the bolt F to permit it to slip notches in other direction of movement of rod D.

On top of rod D there is a round projection d on which there is placedwhen desired a weight l shown dotted in Figs. 1 and 2. Into thebottoni of thecylinderA there are cocks G 9'' G G'connccts to a beer fountain not shown. G is a drain cock. g connects a rubber pipe G which connects a cock g in the beer keg B. In the top of the beer keg B there is a vent cock G shown in section in trying to'preventr 7 'The operation of the device is: thus: The
